DOORLOCK.

. Application filed October 28, 1922.V Serial No. 597,443-` `To all wlw/m, may concern: Be it known that I, HARRY N. SonnNsoN,

a citizen of the United States,` and a lresiuse in connection with automobile doors.

"The object of the invention is the provision of an improved and highly efficient lock of this character which is strong and durable in? `its construction and capable of being 4operated from a knob at one side of the door or by a lever at the other side thereof toretract the locking catch. Other advantages of the invention will be apparent from the following detailed description thereof.

lVhile the invention in its broader aspect is capable of embodiment in numerous forms, a preferred embodiment thereof isv illustrated in the accompanying drawings, in which,

Fig. 1 is a fragmentary side elevation of an automobile body and door equipped with my invention. Fig. 2 is an enlarged horiA Zontal section thereof. Fig. 3 is an outer side elevation .of the lock removed from the door. Fig. 4 `is 'an inner side elevation thereof with a part broken away. Fig.` 5 is an edge View of the outer end portion of the lock with a part broken away, and Fig. 6 is a section on the line 6-6 in Fig. 3.

Referring to the drawings, 1 designates an automobile body having a door opening 2 therein, and 3 adoor for closing said opening'. i A striker plate 4 is set into an edge portion of the `door opening, being i preferably inclined with respect to the outer side of the body, as: shown in Fig. 2, and having its nose `portion terminating in a catch lug 5, the outer end of whichtapers to the outer end of the plate, as shown at 6, to facilitate a ridingof the catch member of the loclithereover during a closing of the door.

The lock proper comprises a body plate 10, which is rigidly mounted against the inner side of the doorframe, the frame being recessed at 11 for receiving a portion of the mechanism carried by the plate. The outer end of the` plate has an arm 12 projecting therefrom and bent laterally to lie within a recess 13 in the outer swinging edge of the door frame, and the side edges of the arm 12 are formed, in slgihtly spaced relation to theedge of the plate 10i, with side wings 14 which are bent outward in 'parallel re lation and at right angles to the body por `tion of the 'arm 12 to cooperate therewith `to forma channel member.

of the wings 14 are provided with outward T he outer ends projecting extensions 15 which lap the inarginal edge walls of the recess 13 and are provided with perforations forv receiving securing screws;

A catch member 16 is mounted in the channel member 1 2, 14 longitudinally thereof, being pivoted at one end .portion thereof to the side walls 14 of the channel at the inner end of the channel, with respect to the door, and then projecting toward and terminating at its free or swinging end adja-- cent to the opposite `end. of the channel. The catch member 16 is preferably made of a strip or length of sheet steel or flat lbai" metal bent in U-shape, with the loop portion thereof forming the nose of the catch andwith the outer terminal endsof its legs piv? oted to the channel sides 14. The plane of projection of the channel arm 12, 14- from the platelO` is substantially that of the `the catch member 16 by a cross-pin 20, so

that longitudinal movements of the link willimpart rocking movements to the catch member. The other end ofthe link is connectedby a pivot 21 to a control lever 22 which. is pivoted at one end, as at 23 tol an extension 24 of the plate 10` and has its opposite end. projecting `in exposed operating position at the inner side of the door.

The

lever at a point above the pivot 21 projects through a guide slot 25 provided in a. laterally projecting flange 26 of the plate 10, and a short distance above such flange is laterally ollset to adapt it to project from the inner side of the door and thence in e2;- posed operating position substantially parallel to the door. A finger 27 projects from the lever 22 and is connected by a coiled. contractile spring to the plate 19. This spring exerts a pressure on the lever which normally retains the nose of the catch 16 projected outward with respect to the channel member 12, lil'in which it is mounted.

To facilitate the operation of the catch member 16 from the outer side of the door, a lever 29 is fulcrumed to the inner side of the frame plate 10 with one end projecting into a slot 30 in the link 17' and with its other end connected by a coiled contractile spring 31 to a linger 32 projecting from the inner end of the plate 10. The spring 31 normally retains the lever 29 in released position with respect to the link 17 and the slot 30 in the link is of sufficient length to permit movements of the link independently of the lever 29. A rotatable hand grip 33 is disposed at the outer side of the door and has its shaft 3l project-ing into the door and into a socket 35 in the hub 36 of the lever 29 so that the lever 29 can be moved against the tension of the spring 31 by a turning of the member 33. Then the control member 33 is so turned the lever 29 acts against the inner end wall of the link slot 30 and imparts a retracting movement to the link and catch member 16.

lVhen the door is in closed position the nose portion of the catch member 16 is adapted to engage the inner side of the catch lug 5 of the striker plate l to retain the door in closed position. When the lock members are fitted in the door and casing the pawl 16 should stand in substantially parallel relation to the striker plate l when in engagement one with the other, as shown in Fig. 2, the pawl in such position being disposed considerably within the limit of its outward rocking movement. This enables the pawl to move out to compensate for wear and for a swinging apart of the door and casing so that a tight engaging oi" the pawl with the striker plate may be iusured at all times when the door is closed. It will be understood that when the door is open the nose portion of the catch member 16 projects beyond the outer end of the channel member 12, 14- and beyond the position which it is shown in the .figures as a. suming, and upon a closing` of the door the cross bar at the nose portion of the catch member engages the tapered nose portion 6 of the striker plate and is retracted thereby to permit the plate to pass to the rear of the lug 5.

I Wish it understood that my invention is not limited to any specilic construction7 arrangement or form of the parts, as it is capable of enibodiment in numerous forms without departing from the spirit of the claims.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is,-

1. ln a lock of the class described, a frame plate having a channeled member projecting laterally from one end portion thereof, a U-shaped catch member pivoted at the terminal ends of its legs Within the channel member and extending longitudinally thereof, an operating link pivotally connected at one end to the leg portions of the catch member and extending through the bottom of the channel member and along the adjacent side of the frame plate, and a manually controlled operating lever carried by the plate and operable to effect a retraction of the link and catch member and normally operating to project the catch member with respect to the channel member.

2. In a lock of the class described, a frame plate having' an arm projecting laterally from one end thereof, the arm having side wings cooperating therewith to form a channel member with the channel facing outward with respect to the plate, a catch member pivoted at one end in the channel, a link pivoted to the catch member and projecting through the bottom portion of the channel along the side of the frame plate, and operating means connected to the link normally operable to project the nose of the catch member outward relative to the channel and manually operable to retract the catch member.

3. ln a lock of the class described, a frame plate, a part projecting laterally from one end thereof and forming a channel member with its channel facing outward with respect to the plate and extending transversely of the plate, a U-shaped catch member pivoted at the terminal ends of its legs within the channel to respective side walls thereof, and means carried by the plate in connection with the catch member through the channel bottom and normally operable to project the free end portion of the catch member outward with respect to the channel member and manually operable to retract the catch member.

4l. In a loc-k of the class described, a striker plate having a catch lug at one end thereof with the outer side of the lug tapered, a frame plate having a channeled part projecting laterally from one end thereof with. the channel facing ont-ward relative to the plate and toward the striker plate, a U- shaped catch member pivoted at the terminal ends of its legs within the channel part to the side walls thereof and extending lengthwise of the channel, the cross bar of the catch member forming its catch nose and adaptedto ride over a tapered lug of `the a `link projecting from the catch member, control means being normally operable to retain the catch member in outwardly pro `jectecl position and being manually operable to retract the catch member from suchpostion, and respective frame parts carrying the striker and frame plates.

In testimony whereof I have hereunto signed my name to this specication.

HARRY N. SORENSON.
